COMBING-MACI-IINE.

Application filed October 29, 1919.

T 0 all whom it may concern:

Be it known that I, HARRY TUNSTALL, a subject of George V, King of Great Britain and Ireland, residing at Fairhaven, in the county of Bristol and State of Massachin setts, have invented a new and useful Improvement in combing-Machines, of which the following is a specification.

Cotton fiber is short and very fine. In its progress through a combing machine the lap passes over what is known as a cushion plate against which it is led by a teed roll which rests on top or" it, the cushion plate serving to support the under surface of the lap and forming part of the nipper system. The cushion plate is made of metal and is presumably smooth, but minute projections exist on its upper surface which engage the libers forming the under surface of the lap and prevent the lap from being properly :led, causing the fibers on its under surface to drag and be looped or doubled and drawn out of parallel relation with their neighbors, so that more waste is produced than is desirable.

The purpose of this invention is to overcome these faults as far as possible by providing the upper side of the cushion plate with a supporting surface which shall be mathematically smooth, for this purpose being made 01" some fine grained metal or a metal. which is so plated as to produce a glazed surface, that is, a surface which is practically as smooth as glass, or it may be made of porcelain or the like. Anyone skilled in the art will appreciate that there are a number of materials which may be used for this purpose either by themselves or as a plating to a metal foundation. I prefer to inlay the ordinary cushion plate with such a glazed plate.

My invention will be understood by refcrence to the drawings in which Figure l is a plan of such glazed plate;

Fig. 2 a view taken at one end thereof.

llig. 3:3 is a plan of the cushion plate with a glazed plate attached thereto showing the position of the feed roll upon such plates, and

any desired shape so long as it receives upon it the lap and leads it oil to the hooked end 6 of the cushion plate B. The glazed plate is attached to the cushion plate by screws (4 preferably near its rear edge. 0 is the feed roll and c is the lap which passes under the :fee'd roll and over the cushion plate into position to be combed at the proper time. The means of mounting the cushion plate and the feed roll are not shown as they are well known in the art.

It will be noticed that by making the plate of thin metal and attaching it near its rear edge its tendency will be to spring up against the roll and hold the lap in close contact with it.

I have used the term glazed to express a condition of microscopic smoothness,one not attained in ordinary construction without great expense both of material and labor.

l Vhat I claim as my invention is 1. In a combing machine, means for feeding the sliver comprising a feed roll and a cushion plate having a glazed upper surface adapted to cooperate with said feed roll to feed the fibers of the sliver whereby said fibers will be delivered by said. feed roll in the same relative relation to each other as that in which they are delivered to said teed roll and cushion plate.

2. In a combing machine, as a means for feeding the sliver, in combination, a cushion plate and a feed roll adapted to press the sliver against, and feed it over, said cushion plate, the feeding surface of said cushion plate being glazed in character, whereby the fibers will be discharged from said cushion plate in the same relation to each other as when received upon it.

3. in a combing machine, as a means for feeding a sliver, a feed roll and a cushion plate having a thin glazed plate mounted thereon, means for attaching said glazed plate to said cushion plate near the rear edge thereof whereby the front edge of said glazed plate will tend. to spring up against said feed roll and hold the sliver in close contact therewith and said sliver will be fed freely and without deformation of its fibers by said feed roll.
